15 Claims. (Cl. 14093) This invention relates to machines for equipping Wired box parts with fastening means, and particularly to machines for manipulating a wire secured to a box part to form and perpetuate a bight on the end of the wire.

It is an object of the invention to provide certain improvements in a machine of the type disclosed in U. SQPate nt to Rosenmund No. 1,933,031.

It is a further object to provide such a machine with improved means for positioning the box part relative to the wire-manipulating elements to locate the fastening means a predetermined distance from the box part edge.

It is a further object of the invention to provide such a machine with safety means adapted to prevent an operation of the machine unless the box part is correctly positioned for a wiremanipulating operation.

It is a further object of the invention to provide a safety device of the character referred 5 shown to which is controlled by the position of the box part, thus insuring a correct location of the fastening means relative to the box part.

One illustrative embodiment of the invention is in the accompanying drawings, in which:---

Figure 1 is a perspective View of a pair of wire connected box blanks upon which the machine is designed to operate.

Fig. 2 is a perspective View of a box blank after it has been operated upon by the machine of this invention and showing the character of fastening means supplied by the machine.

Fig. 3 is a perspective view of a completed box formed by folding the blank of Fig. 2 into box form about end sections and interengaging the fastening means.

Fig. 4 is a diagrammatic view of the wiremanipulating elements of the machine and. showing in dotted lines the initial position of the wireconnected box blanks on their supporting table prior to a wire-manipulating operation and, in full lines, the position of the box parts and the supporting table when they have been lowered to present the wires to the wire-manipulating elements.

Fig. 5 is a top plan view of the supporting table with certain parts left out to disclose more clearly the box part positioning means.

Fig. 6 is an enlarged top plan view of one of the box positioning devices in operative position.

Fig. '7 is a similar view showing the positioning device in its non-operative position to permit the removal of the completed box part after a wiremanipulating operation.

Fig. 8 is a side elevation of the foot pedal for operating the clutch to throw the machine into operation and showing the safety device for preventingop'eration of the pedal except when the box part is in correct position relative to the wire-manipulating elements. n

Fig 9 'is an enlarged detail showing the cam means for moving the positioning devices to non-operative position after a box blank has been correctly positioned relative to the wiremanipulating elements.

Referring to Fig. 1, the machine of this application is intended to receive on a supporting table the wire-connected box parts designated A and B and to sever the connecting wires designated C, form prongs on the severed ends, swing the prongs over onto the box parts to form. bights, and to drive the prongs into or through the box parts to perpetuate the bights. The completed bights thus formed are shown in Fig. 2 and designated D.

When the blank shown in Fig. 2 is folded into box form as shown in Fig. 3, the fasteners D may be passed onethrough the other and hooked to complete the continuity of the wire binding.

As shown in Fig. 4, the wire-connected box parts A and B when fed into the machine are positioned on a table or support I, which is adapted to be lowered to present the connecting wires C to the wire-manipulating elements.

It is desirable that the box parts A and B be correctlylocated or positioned before the wires 0 are presented to the wire-manipulating elements. This is accomplished by definitely positioning the front edge of the box part B prior to starting the machine. Definitely positioning the box part B also definitely positions the box part A, because the length of the Wires connecting the two box parts are of definite predetermined length. Thus, when the box part B is definitely positioned relative to the wire-manipulating elements, the length of the connecting wire will definitely position the box part A.

To definitely position'the forward edge of the box part B relative to the wire-manipulating elements, stop mechanism'is provided which normally lies in the path of travel of the box part B and. arrests movement of the box part B when the box part strikes the stop mechanism and moves it to the limit of its travel. After the box part has been definitely positioned against the stop mechanism and the machine started, the stop mechanism is withdrawn from in front of the boxt part and held in non-stop: position during a Wire-manipulating operation. The stop mechanism of this invention will be described in detail hereinafter.

Associated with the stop mechanism and controlled thereby is a safety mechanism for preventing operation of the machine except when the box part is properly positioned for a wire-manipulating operation. be described in detail hereinafter.

When the box parts have been correctly positioned on the supporting table I, the machine may be started by throwing into operation a one-cycle clutch. When the machine is started the table I-- is lowered to present the connecting wires C to the wire-manipulating elements which sever the wires to form prongs on the severed ends, swing; the prongs over onto the box parts, and drive the prongs into or through the box parts.

The wire-manipulating elements and. their"? operation are fully shown and described .in

the aforementioned patent to Rosenmund No.
